HORSESHOE-CALK.

. tion for horse shoes which will permit of in use. With the above and other objects in view the calk being readily attached andwill prevent of its being accidentally removed and which prevents the turning of the calk the invention consists in the horse shoe calk as herein claimed and all equivalents.

Referring to the accompanying drawings in which like characters of reference indicafe the same parts in the different views:

view of another form of ing Figure 1 is'a plan view of a horse shoe provided with ance with this invention, two of the calks being shown in section; Fig. 2 is a sectional view thereof; Fig. 3 is a-detail View of one 'of the calks; and, Fig. 4 is a perspective calk showing the locking recess therein.

In these drawings 10 indicates the shoe proper which at the desired places for the calks is provided with raised bosses ll havtapering openings 12 through them and through the shoe'as shown in Fig. 2. Each boss has an integral lug 13 standing up from it at one edge thereof and the calk 14 ,which has a tapering shank to fit the tapering opening 12 is provided with a recess 1.5 in the side of the shank into which the lug 13 may be driven to serve as a key for locking the calk in place. The recess 15 is of varying width with its narrow portion lowermost as shown in Fig. 3 and has its bottom or rear'wall inclined in the opposite direction from the. inclination of the wall of the opening 12 at the point of location of the ilugl3 so that when the lug is driven over and down into the recess 15 behind the boss 11 it not only serves as a key for preventing the turning of the calk, but it constitutes a wedge fitting between oppositely inclined surfaces of the calk and the boss to effectively lock the calk 'in its seat against removal.

In operation the shoe is attached irthe Specification of Letters Patent. Application filed April 1, 1912. Serial No. 687,822.

usual manner and the calks are inserted in the openings 12 and are struck with a hammer to drive them firmly on their seats, care being taken that opposite the lugs 13. Then the lugs 13- are into the recesses means of a pointed tool'tvhich will reach in between the head of the calkand the boss 11 and the operation is continued until the 35 lug'is driven downwardly to fill the space recess 15 and the tapering walls of the calk seat. WVhen so connected the calk is incapable of turning in its seat,-t-he'lug 13 the recess 15 and any. outward movement of the calk is prevented by reason of the wedge. like action of the lug 13 which has been forced tightly between the oppositely inclined walls of the recess and the Any tendency of the calk to move-out of its tightly clamp'the wedge lug 13,between the tapering side walls of the recess 15 and between the on positely inclined walls of the calk seatand 0 the bottom of the recess and so accidental removal of the calk is effectively prevented. By means of this calk connection, the calk may be removed when desired for substituting new calks by which will crowd the metal forming the key out of the way and when this has been done 4 a new calk may be placed in position and locked by driving the lug back as before.

By means of this invention a shoe may be 90 provided with wearing calks suitable to the season and the calks may be changed as required without the liability of the calks becoming lost or working loose.

What I claim as new by Letters Patent is:

'1. A. horse shoe provided with an opening forming a calk seat, a calk having a shank to fitthe calk seat and provided with a recess of tom wall, and a lug on the horse shoe at the edge of the calk seat adapted to be driven into the recess and occupy the space between the wall of the calk seat and the inclinedwall of the recess.

2. A horse shoe provided with a tapering opening forming a calk seat, a calk having a tapering shank to fit within the calk seat and provided with a recess in the side of its shank and with its bottom posite to the inclination of the wall of the calk seat, and a lug on the horse shoe at there'cesses .15 stand acting as a key within calk seat.
